没有调用onserverclick按钮 [英] not calling that onserverclick button

问题描述

我希望在C＃，asp.net中执行服务器点击事件方法。我为删除按钮创建动态id，但它没有调用该服务器事件，它当前不适合我，但它转到页面加载事件，但不调用onserverclick按钮事件。在click事件中，我编写了一组已调用的代码。

Hi,

                                    {
                                        sFinal = sFinal + sSlider.Replace("<bid>", "btn" + i.ToString());
                                        i++;
                                    }

推荐答案

Html按钮没有onserverclick方法。请参见 http://www.w3schools.com/tags/tag_button.asp [ ^ ]您可以设置要提交的类型以便将页面发回。



或者，您可以动态添加按钮，但这是通过使用C＃代码完成的，而不是构建字符串。 Google用于c＃动态添加按钮。

Html buttons do not have a onserverclick method. See http://www.w3schools.com/tags/tag_button.asp[^] You could set the type to submit for it to post the page back.

Or, you can dynamically add a button but this is done by using C# code, not building a string. Google for "c# dynamically add button."

要使ASP.NET引擎识别您的按钮，您必须将它们添加到页面的对象模型而不是字符串...

For the ASP.NET engine to recognize your buttons you have to add them to the object model of your page and not as a string...

while (i < dt.Rows.Count)
{
  Button oBtn = new Button();

  oBtn.ID = string.Format("btn_{0}", i);
  oBtn.Click += new EventHandler(btnDelete_ServerClick);
  // set any other property here...

  Page.Controls.Add(oBtn);
  i++;
}
